Ben Stiller and Christine Taylor continued their Hawaiian vacation with a day at the ocean yesterday. Ben Stiller was shirtless again after soaking up the sun earlier this month while his wife lounged in a bikini. The couple are in Kauai on an extended getaway with their family, and Christine celebrated her 40th birthday with an evening bash in the sand during the trip. Jennifer Aniston and Justin Theroux were on hand for the festivities, and while the loved-up duo have since left the island, another famous family recently popped up in the tropical locale. Bikini-clad Julia Roberts had a beach day with her husband, Danny Moder, and their kids, Hazel, Phineas, and Henry.
